What is the secondry voltage of 420kV Current Transformer ,
the rated current is 2600A
Answers were Sorted based on User's Feedback
If the rated current of the CT is 2600/5 amps, then the
secondary voltage will be (420000x2600)/5= 218400000
(i.e.218400kv)
Is This Answer Correct ? | 5 Yes | 1 No |
Correction to answer: If the secondary is open voltage will
be 218400 kv and it will be '0', if it is shortcircuited

Answer / sathiyaseelan.m
I dont thing 420kV CT available. If it available CT
secondary voltage is proposnal to Burdon. Ex if a meter
takes 10VA if CT sec. 5A than Voltage will be 2V

Answer / ashish patil
secondary voltage is 0. Bcz it is current transformer which
has short circited secondary. O/p is 1A.
